How many valence electrons does heluim need to have a filled outermost energy level?
Helium only needs 2 valence electrons to have a filled outermost energy level.
How many valence electrons does helium need to gain to have a filled outermost energy level?
0 It already is full
An atom is stable when its outermost orbit is?
It is stable when filled with electrons.
Do noble gases have the maximum number of electrons in their outer energy level?
Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.
Why do valence electrons determine the reactivity of an atom?
The valence electrons are the outermost electrons. In an atom, its lower energy levels have been filled and are therefore stable. But, except for the noble gases, the valence energy level is not filled, and therefore not stable. So atoms must undergo chemical reactions in order to fill their valence shells and become stable. They can do this by sharing electrons, transferring electrons, or by forming a sea of electrons shared by all the atoms.
How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
How many electrons are in the outermost level of carbon how many electron does it need to have fill this energy level?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
How many valence electrons does heluim need to have a filled outermost energy level?
Helium only needs 2 valence electrons to have a filled outermost energy level.
How many electrons does it need to have in the outermost energy level filled?
8 electrons
What are the electrons in the outermost energy level of an atom are called?
Completely filled octet.
The electrons that occupy the outermost filled shell are called?
Outer energy level electrons, or valence electron.
What are the set of 8 electrons in an atom's outermost energy level called?
Completely filled octet.
How many valence electrons does helium need to gain to have a filled outermost energy level?
0 It already is full
Why do atoms join to other atoms?
To become stable. When the outermost energy field is filled to maximum electrons, the atom is stable.
An atom with an incompletely filled outermost energy level is likely to be?
An atom with an incompletely filled outermost energy level is likely to be reactive. This is because it wants to acquire a filled outermost energy level.
An atom is stable when its outermost orbit is?
It is stable when filled with electrons.
Why is a helium atom stable with only two electrons in its outermost energy level?
helium has completely filled valence orbitals and hence is stable
